Aerial vehicles including one-dimensional arrays of transmitters and receivers aligned perpendicular to one another are configured for safe operation. The transmitters may be configured to transmit signals at designated times in order to generate synthetic waves having common fronts from selected angles. The receivers are configured to capture data regarding reflections of the synthetic waves from objects, and to interpret the data to determine bearings or angles to such objects. Locations of the objects may be determined based on angles at which the synthetic waves are transmitted and bearings or angles to the objects that reflected the synthetic waves, as well as times at which reflections of the synthetic waves are received. Maps or other representations of objects on a scene may be generated based on such locations.

8. The method of claim 7, wherein each of the delay times is calculated by dividing a product of the second distance and a sine of one of the angular intervals by the speed of the at least one of the first energy or the second energy.
10. The method of claim 9, wherein each of the delay times is calculated by dividing a product of the first distance and a sine of one of the plurality of angles by the speed of the first energy and the second energy in the medium.
This invention relates to a method for determining delay times in a system involving the propagation of energy through a medium. The method addresses the challenge of accurately calculating time delays for energy signals traveling different paths in a medium, where the paths are defined by varying angles and distances. The system involves a first energy source and a second energy source, each emitting energy that propagates through a medium at a known speed. The method calculates delay times for each path by dividing the product of a first distance and the sine of an angle by the speed of the energy in the medium. The angles correspond to the directions of the energy paths relative to a reference, and the first distance represents a fixed or variable separation between the energy sources or other system components. The method ensures precise synchronization or timing adjustments in applications such as signal processing, imaging, or communication systems where energy propagation delays must be accounted for. The calculation accounts for variations in path length due to angular differences, enabling accurate delay compensation in dynamic or multi-path environments. The technique is particularly useful in systems where energy propagation speed is constant but path geometry varies, such as in phased arrays, sonar, or radar applications.
